The island was formed during the recent retreat of the falls as it cut inward through the Niagara Escarpment. The Niagara River's channel splits in two above the falls, creating two sets of falls, one on either side of the island. In 1959–60, the island's eastern side was extended about for additional parking and a helicopter pad. Fill was provided from excavation for the construction of the Robert Moses State Parkway. In 1955 the area between the Terrapin Rocks and Goat Island was filled in, creating Terrapin Point. In the early 1980s, the United States Army Corps of Engineers filled in more land and built diversion dams and retaining walls to force the water away from Terrapin Point. All together of the Horseshoe Falls was eliminated, including on the Canadian side. According to author Ginger Strand, the Horseshoe Falls is now entirely in Canada. Other sources say "most of" Horseshoe Falls is in Canada. The island's western end is slowly being eroded by the falls and the entire island will eventually disappear as the falls erode further upstream. The waters around Goat Island are relatively shallow and studded with islets and rocks, many of them scenes of dramatic rescues and rescue attempts.
History
John Stedman—an early pioneer and miller—kept a herd of goats on the island. Upon returning to the island after the terrible winter of 1780, he found all but one of them had died, thus giving the island its name. The island's preservation as parkland is due to the early efforts of Augustus Porter, who in the middle 19th century recognized the long-term value of the falls as a tourist attraction. Porter purchased the island and allowed a group of TuscaroraNative Americansto live on it and sell their crafts to the tourists who came to the falls by stagecoach and early railroads. In spite of pressure, Porter refused to tame the environment on the island. In 1817, he built a toll bridge to the island for tourists. It was swept away by ice, so another was built the following year downstream. Basil Hall called it "one of the most singular pieces of engineering in the world". Almost seven hundred feet long, it soon became the region's best-travelled walkway. In 1885, the island was included in the Niagara Reservation State Park which is the oldest state park in the U.S.
Tesla Monument
The island is home to the Tesla Monument which honors the Serbian-American inventor, Nikola Tesla. The statue was given to the United States by the government of Yugoslavia in 1976. The statue's sculptor is Frano Kršinić, a renowned Yugoslav sculptor. In mid-2016, the statue was moved to Stedman's Bluff, the section of the island that overlooks the Bridal Veil Falls and the American Falls, to increase popularity.
Botany
In 1879, landscape architect Frederick Law Olmsted, wrote that he had travelled four thousand miles throughout the continent "without finding elsewhere the same quality of forest beauty which was once abundant about the falls, and which is still to be observed in those parts of Goat Island where the original growth of trees and shrubs had not been disturbed..." Olmsted concluded the spray from the Falls created a natural nursery for indigenous plant life. Since that time, regular mowing of the Goat Island meadow, heavy foot traffic, and the incursion of invasive species have significantly changed the island's floral landscape.
In fiction
Part of H. G. Wells's 1908 novel The War in the Air is set on Goat Island. During the fictional invasion of the U.S. by the forces of Imperial Germany, depicted in the book, the protagonist is stranded on the island, with bridges to the mainland having been destroyed in the fighting, and is involved in a grim battle for survival with two equally stranded German soldiers.
